Make sure you have your Netflix page and twitch page are open (Dont forget to log into twitch).Your twitch page should be twitch.tv/(your username)First of all, on your twitch page, click on the setting option located on the bottom of your chat box:

Then click on the popout option, so your chatbox can appear on a separate window, I just like to so this since I wont have to be on my livestream page to see the chat, like so:

You can then just close your twitch page and just have the chat box openNow that thats sorted, its time to actually set up the live stream. Open up OBS, and then open up your window for Netflix.Make the Netflix window smaller like so:

Then go to the broadcaster, right click the white space in Sources section, choose add, and then choose the option Monitor Capture:

It will ask you to name it, name it anything you want. Mine is called Anime Livestream 2.The Monitor capture options will appear, if you have more than one monitor then there is an option at the top to choose which monitor you want to livestream, if you just have one then just press OK at the bottom.Now preview the livestream by pressing Preview Livestream at the bottom right of the broadcaster, and you will see that the livestream is of your whole desktop:

Lol it looks a bit weird at first but were about to fix that! Okay to fix this, make sure you can see the whole of the Netflix screen so that the broadcaster isnt covering any of the video but also make sure you can still see the sources section on the broadcaster like so:

Next step is to right click the livestream you want to broadcast, for me it would be Anime Livestream 2, and then click on properties:

The Monitor Capture options will then appear. Again, move box to the side so you can see the whole netflix video. It might be a bit difficult to see but you need to tick the Sub-Region box in the middle of the window, and then click on Select Region:

Your whole screen will then appear shaded:

What you will now do is select which region of your screen you would like to livestream. So you will adjust the shading so it will just cover the Netflix video like so:

Once youve adjusted it press enter and then press OK at the bottom of the Monitor Capture options. Since you selected a region of your screen, the rest of the livestream appears black while the section your chose is being shown:

To fix this, simply press Ctrl+F on your keyboard and the section you picked will fill up the whole screen:

Now all you have left to do is stop the preview livestream (click on Stop Preview), and start streaming for real by clicking on Start Streaming. Make sure the broadcaster window is out the way so it doesnt cover the video, so you can just minimize the broadcaster at this point.You can then watch and chat to those watching on twitch too with the twitch chat box we opened earlier like this:

Oh! I forgot to mention one more thing. On the broadcaster, it has two sets of sounds being broadcasted, your mic and the sound from your computer. Make sure you click on the mic one so that it doesnt show any colour, this makes sure the livestream doesnt pick up your mic sounds:
